What was most unexpected was the length of the third interview. Covered a lot of different areas including real world project experience, methods and frameworks, business and technology. Might be an idea to have some references open on your computer as reminders (ITIL, Prince2, TOGAF). But this will only work as reminders. They were all good questions though and nothing to intentionally catch you out. They just wanted to check you knew your subject.

I have a lot of experience in the IT industry but especially as an Enterprise Architect, I feel I would be very suited to this role. I also gave some examples if work I had done in the past that were similar to the Three role.
